Hello there! Well, I can’t say anything about this problem other than it’s just super easy. Allow me to show you:

Given a list of space separated words, reverse the order of the words.

If that first sentence didn’t kill it for you, I don’t know what will. Anyway, the python code (validated, of course): 

for case in range(1,int(raw_input())+1):           # For all test cases
    words = raw_input().split(" ")                 # Get the list of words
    words.reverse()                                # Reverse word list
    print "Case #%d: %s" % (case, " ".join(words)) # Reports results, add spaces

Can’t get easier than that. And I actually had to learn that reverse() does not return the reversed list… in a perfect world, it could be solved within the print line, with:

    " ".join(raw_input().split(" ").reverse())

But, maybe next time… 😀 See ya, warned you it was real quick!
